退伍军人截肢者表现出保留的力量,但需要改进的步态训练,以防止未来的肌肉骨损伤. 这项研究量化了步态和力量,以告知更好地康复长期健康.

科学领域:

  • 生物力学和康复科学.
  • 对退伍军人截肢人口的研究.
  • 肌肉骨健康和衰老.

背景情况:

  • 截肢的退伍军人面临着随着年龄的增长而出现并发症的风险.
  • 有限的研究量化了老兵截肢者的步态和力量.
  • 需要研究与肌肉骨损伤风险相关的步行参数和下肢强度.

研究的目的:

  • 量化退伍军人截肢者的关键步行参数和下肢力量.
  • 检查步态,力量和肌肉骨损伤的潜在指标之间的关系.
  • 为了确定改进退伍军人截肢者的康复策略的领域.

主要方法:

  • 在6分钟的步行测试 (6MWT) 中,利用3D运动捕捉和力板进行步行分析.
  • 使用异动力动力计测量了膝盖延伸/屈曲峰值等比扭矩和腿筋:四肢骨 (H:Q) 比率.
  • 匹配单边穿骨 (UTT) 和单边骨 (UTF) 截肢队伍与有能力的对照.

主要成果:

  • 截肢者表现出低于推的H:Q扭矩比率,表明潜在的步态不平衡.
  • 在受伤12.5年后的队列之间没有观察到完整的膝盖扭矩的显著差异.
  • 与对照组和UTT截肢者相比,UTF截肢者在6MWT期间的步行速度和距离显著降低.

  • 在6MWT的后期阶段,在两组截肢者中都注意到了动力不对称性,这表明可能存在膝关节关节应力.

    • 结论:

    • 英国的老兵截肢者在康复后表现出强大的完整四肢力量.
    • 亚最大运动揭示了增强截肢者的步行功能的机会.
    • 专注于生活质量的个性化康复可能会延迟老兵截肢者肌肉骨并发症的出现.
